Network Connectivity Problems

Use when the VM is running but unreachable due to Azure network configuration: NSG, routing, NIC, public IP, or DNS.

Symptoms -> Solutions

Symptom OS Action Docs
no NSG allow for RDP/SSH Any Add inbound TCP 3389/22 from approved source RDP NSG
NIC and subnet NSGs conflict Any Traffic must pass both; inspect effective rules Traffic filter
UDR sends traffic to NVA Any Check effective routes and NVA forwarding Routing
no public IP Any Add public IP or use Bastion/private path Public IP
guest NIC disabled/down Windows/Linux Enable NIC via Run Command or Serial Console RDP NIC / SSH overview
static guest IP misconfig Windows/Linux Restore DHCP guest config Reset NIC / SSH overview
ghost NIC after disk swap/resize Windows Reset network interface Reset NIC
DNS failure Any Check DNS; Azure default is 168.63.129.16 DHCP

Quick Commands

az network nic list-effective-nsg --name <nic> -g <rg>
az network nic show-effective-route-table --name <nic> -g <rg> -o table
az vm list-ip-addresses --name <vm> -g <rg> -o table
az network watcher test-connectivity --source-resource <vm-resource-id> \
  --dest-address <ip> --dest-port <port> -g <rg>

Linux guest NIC commands use VM agent/extensions. Run Pre-Flight Safety Checks first.

az vm repair reset-nic --name <vm> -g <rg> --yes
az vm run-command invoke --name <vm> -g <rg> --command-id RunShellScript \
  --scripts "ip link show; ip addr show; ip link set eth0 up && dhclient eth0"

    This skill is designed for Azure diagnostics and troubleshooting, providing a comprehensive set of guides and scripts that utilize standard tools like the Azure CLI and kubectl. It includes some security considerations, such as the ingestion of logs which provides a surface for indirect prompt injection, and the use of privileged debug pods for advanced diagnostics. These are used within the skill's intended functionality and are accompanied by appropriate guidance for user approval.
